Summary:
This diff adds a prototype of a new checker that collects config checkings between markers.
Basically, what the checker is doing is a taint analysis.
* Taint source: function calls of "marker start"
* Taint sink: function calls of config checking
* Taint remove: function calls of "marker end"
By the taint analysis, the analysis results will say that which taints can reach to the sink. In other words, which marker ID that has been started can reach to the config checks, before marker's ending.
I am separating the diff into three steps:
(1/3) Add basic abstract semantics
(2/3) Add trace information
(3/3) Add reporting with test examples

Summary:
This models ARC implementation of dealloc, see https://clang.llvm.org/docs/AutomaticReferenceCounting.html#dealloc. Dealloc methods can be added to ObjC classes to free C memory for example, but the deallocation of the ObjC instance variables of the object is done automatically. So here we add this explicitly to Infer:
1. First, we add an empty dealloc method when it is not written explicitly.
2. For each dealloc method (including the implicitly added ones) we add calls to dealloc of the ObjC instance variables.

Delete the following outdated pages. Some of them have better
replacements now but some of them are just too out of date to easily
salvage.
- 01-adding-models.md: this is biabduction-specific and hard to make
that distinction. Most checkers have no way to add models. Even
suggesting that people add their own biabduction models was a bit
awkward as it requires recompiling infer to use.
- 01-checkers.md: outdated document that describes "new" checkers like
Quandary :)
- 01-experimental-checkers.md: very outdated!
- 02-limitations.md: also outdated: it roughly says "we don't do concurrency or
arithmetic, the former is basically impossible but the latter should
be easy"... well, 5 years later this hasn't aged too well ;)
- 01-eradicate.md: content has moved to auto-generated documentation

Summary:
This provides some of the infrastructure needed for documentation issue
types within infer itself so we can generate the website and keep it up
to date when introducing new issue types.
Basically each issue type has documentation in its datatype in OCaml
now. But, documentation strings can be several pages of text! To avoid
making IssueType.ml even more unreadable, add the option to write
documentation in long form in files in infer/documentation/issues/.
This implements `infer help --help-issue-type` and show-cases how
documentation works for a couple of issue types. Next diff bulk-imports
the current website documentation in this form.
